How does an airline become placed in the Low-Cost Carrier category?

For the Low Cost Carrier (LCC) category, we consider the top 90% of airlines by flights, seats and ASKs that are industry recognized and/or self-identified as Low Cost Carriers. A minimum coverage threshold of 80% must be met to be considered for this category. We currently follow the International Air Transport Association (IATA)'s designation of a Low Cost Carrier.
